Holo-krome 76136 M5 X 0.80 Hex Socket Cap Screw 35mm

Product Description

The HOLO-KROME 76136 is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. With an M5 x 0.80 thread size and a 35 mm length under head, this screw is partially threaded and driven with a standard hex socket tool. It is manufactured from alloy steel at material grade 12.9, placing it among the highest strength class available for metric fasteners. The black oxide finish provides moderate corrosion resistance and reduces surface reflectivity. Machinists, millwrights, and maintenance technicians commonly install this hardware where compact, flush-seated clamping force is required.

This screw is suited for precision mechanical assemblies, machine tool components, jigs, fixtures, and structural joints where a recessed drive is preferred over an external hex head. The partially threaded shank provides a shoulder bearing surface, which is useful in applications requiring accurate alignment or shear load distribution. Conformance to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 makes it interchangeable with metric socket cap screws specified to those same international standards across a wide range of industrial and OEM applications.

Key Features

• M5 x 0.80 metric thread, 35 mm length under head
• Alloy steel construction, grade 12.9 for maximum tensile strength
• Black oxide coating for corrosion resistance and low surface reflectivity
• Partially threaded shank provides shoulder bearing and shear load surface
• Hex socket drive for high-torque, recessed installation
• Conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1

Compatibility

Designed as an OEM-style and aftermarket replacement metric socket cap screw for any assembly specifying M5 x 0.80 thread, 35 mm under-head length, DIN 912 or ISO 4762 geometry, and grade 12.9 alloy steel material.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated hex key or socket driver. Always clean and inspect the mating threaded hole before installation and confirm thread engagement depth meets design specifications. Do not mix grade 12.9 fasteners with lower-grade hardware in the same joint without engineering review. Follow applicable torque specifications from the equipment OEM or a recognized fastener standard — no torque values are specified in the product data provided.
